While the character only appeared in a moment at the end of the episode, The CW has now released a better look at what Constantine will be doing when he arrives. Fortunately, for those who've always loved his dark brand of heroism, it looks as though he's bringing his style to Legends of Tomorrow.

In the preview, which you can watch above, Constantine joins forces with the Legends to fight off a brand of evil that they've never exactly dealt with before. Unlike the light-hearted nature of many Legends episodes, this spring premiere will see the team help out Constantine as he tries to perform a dangerous exorcism.

You can check out the full synopsis for the episode, which is titled "Daddy Darhkest," below. Legends of Tomorrow will return on Monday, February 12 at 8pm ET on The CW.

After Sara’s (Caity Lotz) encounter with Mallus, the Legends are paid a visit by John Constantine (guest star Matt Ryan), a demonologist detective.

The Legends agree to accompany him to a present-day psychiatric hospital and they are surprised to discover who Constantine is trying to help.
